Abstract

Silenciador para un sistema de escape de un motor de combustión interna, que comprende: una carcasa (1) que tiene un espacio interior (11), un tubo de entrada (3, 5) para que entre sonido en el silenciador, un tubo de salida (4, 5) para que salga sonido del silenciador, y una pared de separación (2, 22; 58) dispuesta para extenderse desde el tubo de entrada (3; 5) al tubo de salida (4; 5) y que está realizada en una manera tal como para definir un primer y segundo conductos acústicos (581, 21) que se extienden a través de la carcasa (1) para permitir la propagación de sonido a lo largo del primer conducto acústico (581) para entrar en el espacio interior (11) de la carcasa (1) y para salir a continuación del espacio interior (11) de la carcasa (1) de nuevo, y para permitir la propagación de sonido a lo largo del segundo conducto acústico (21) y derivar acústicamente el espacio interior (11) de la carcasa (1), caracterizado porque el silenciador, que incluye el espacio interior de la carcasa, el tubo de entrada, el tubo de salida y la pared de separación, está dimensionado y conformado para formar un filtro de paso alto que tiene una frecuencia de corte que está en el rango de 200 Hz a 800 Hz .Silencer for an exhaust system of an internal combustion engine, comprising: a housing (1) having an interior space (11), an inlet tube (3, 5) for sound to enter the silencer, a pipe outlet (4, 5) for sound to come out of the silencer, and a separation wall (2, 22; 58) arranged to extend from the inlet tube (3; 5) to the outlet tube (4; 5) and which is performed in a manner such as to define a first and second acoustic conduits (581, 21) that extend through the housing (1) to allow the propagation of sound along the first acoustic conduit (581) to enter the interior space (11) of the housing (1) and to then exit the interior space (11) of the housing (1) again, and to allow the propagation of sound along the second acoustic conduit (21) and derive acoustically the interior space (11) of the housing (1), characterized in that the silencer, which includes the internal space or of the housing, the inlet tube, the outlet tube and the separation wall, is sized and shaped to form a high pass filter having a cutoff frequency that is in the range of 200 Hz to 800 Hz.
